It relates to a method for producing an alternative raw material for alumina for cement using aluminum waste dust collecting dust, which can increase added value while preventing environmental pollution by providing it as a raw material, and alumina alternative raw material for cement manufactured thereby.

일반적으로 알루미늄을 주성분으로 하는 주물 제품은 660 내지 800℃의 온도 조건에서 용융과정을 통해 제련 및 주조된다. 특히, 폐알루미늄을 제련공정을 통해 고순도의 알루미늄 주물 제품으로 생산되기까지 많은 공정을 거치게 되는데, 이 과정에서 다량의 알루미늄 폐집진 더스트가 필연적으로 발생된다.In general, a casting product containing aluminum as a main component is smelted and cast through a melting process at a temperature condition of 660 to 800°C. In particular, it goes through many processes until it is produced as a high-purity aluminum casting product through the smelting process, and in this process, a large amount of aluminum waste dust is inevitably generated.

상기와 같이 발생되는 알루미늄 폐집진 더스트에 포함된 성분중 알루미나(AL2O3)가 65 내지 90% 함유되었을 때는 재정련과정을 거처 알루미늄 성분을 회수를 하고, 알루미나(AL2O3)가 65% 이하 함유되었을 때는 폐기물 처리업체에서 유기성 오니를 혼합하여 매립처리를 하고 있으며, 매년 매립 처리되는 알루미늄 폐집진 더스트는 수십만톤에 달하는 것으로 알려져 있다. When alumina (AL 2 O 3 ) is contained in 65 to 90% of the components included in the aluminum waste dust collected as described above, the aluminum component is recovered through a refining process, and alumina (AL 2 O 3 ) is 65 When the content is less than %, waste disposal companies mix organic sludge for landfill treatment, and it is known that the amount of aluminum waste dust collected annually reaches hundreds of thousands of tons.

이렇듯 매립 폐기되는 알루미늄 폐집진 더스트를 자원화하기 위하여 당업계에서 제시한 선행기술로는 특허출원 제10-2013-0112428호(발명의 명칭 : 폐알루미늄 분진과 유동층상 보일러의 비산재를 이용한 아우인계 시멘트 조성물 및 그 제조방법)가 제시되고 있다.As a prior art proposed in the art in order to recycle the aluminum waste dust collected from landfills as such, Patent Application No. 10-2013-0112428 (Title of the invention: Auin-based cement composition using waste aluminum dust and fly ash of a fluidized bed boiler) and a manufacturing method thereof) are presented.

상기 특허출원 제10-2013-0112428호에서는 알루미늄 금속의 용융 후 가공 또는 알루미늄 금속의 제련 후에 발생되어 분진 폭발의 위험성이 있는 폐알루미나 분진과, 대량으로 발생되나 재활용 가치가 거의 없는 국내의 유동층상 보일러에서 발생하는 비산재를 활용하여 전량 수입에 의존하고 있는 아우인계 시멘트 조성물 제조방법이 게시되어 있다.In the above Patent Application No. 10-2013-0112428, waste alumina dust, which is generated after processing after melting of aluminum metal or smelting of aluminum metal, has a risk of dust explosion, and domestic fluidized bed boilers that are generated in large quantities but have little recycling value A method for manufacturing an Auin-based cement composition, which is entirely dependent on imports, using fly ash generated in

상기 물의 온도는 상온상태에 비해 따뜻한 상태로 유지토록 함으로써 반응 속도를 빠르게 진행할 수 있으며, 상기 1차 교반 후 전용교반기 내부에 투입되었던 액상의 물질을 배수 및 탈수하여 제거한다(S200).By maintaining the temperature of the water in a warm state compared to the room temperature state, the reaction rate can be accelerated.

상기 배수 및 탈수제거단계(S200)에서는 과산화수소수(H2O2)와 반응하여 철(Fe), 마그네슘(Mg), 망간(Mn), 구리(Cu), 크롬(Cr) 등의 불순물이 동시에 제거된다.In the drainage and dehydration removal step (S200), impurities such as iron (Fe), magnesium (Mg), manganese (Mn), copper (Cu), and chromium (Cr) are simultaneously reacted with hydrogen peroxide (H 2 O 2 ). is removed

상기 배수 및 탈수 후 50 내지 60℃ 온도의 물 50L를 그 전용교반기에 투입 하여 40 내지 120rpm의 속도로 교반을 하면서 그 전용교반기의 내부에 수산화암모늄(NH4OH) 0.7 내지 1.5L를 투입 후 100 내지 150분 동안 2차 교반을 실시하고(S300), 상기 2차 교반 후 내부에 투입되었던 액상의 물질을 2차 배수 및 탈수 처리한다(S400).After the drainage and dehydration, 50 L of water at a temperature of 50 to 60 ° C is put into the dedicated stirrer, and while stirring at a speed of 40 to 120 rpm, 0.7 to 1.5 L of ammonium hydroxide (NH 4 OH) is added to the inside of the dedicated stirrer 100 Secondary stirring is performed for 150 minutes to 150 minutes (S300), and after the second stirring, the liquid material introduced therein is subjected to secondary drainage and dehydration treatment (S400).

수산화암모늄(NH4OH)을 투입하게 되면 염분에 포함된 염화나트륨(NaCl)이 반응을 하여 용액 내 각각의 양이온으로 공존함으로써 아쿠아(Aqua) 상태가 되는 것이다.When ammonium hydroxide (NH 4 OH) is added, sodium chloride (NaCl) contained in the salt reacts and coexists as respective cations in the solution, resulting in an aqua state.

상기 2차 배수 및 탈수단계에서 수득한 슬러지 상태의 알루미늄 폐집진 더스트(Dust)를 공지의 기계 장치 중 진공 벨트 필터(VACUUM BELT FILTER) 또는 세라믹 디스크 필터(CERAMIC DISC FILTER)에 투입하여 수분함량 5 내지 20% 이하가 되도록 수분을 제거(S500)한 상태로 중량(g) 단위별로 포장(S600) 후 납품을 할 수도 있고, 수분 제거단계(S500)에서 수득한 알루미늄 폐집진 더스트를 1,000 내지 1,400℃ 온도 조건에서 30 내지 60분 동안 소성 공정(S550)을 진행한 다음, 중량(g) 단위별로 포장(S600)을 하여 납품을 할 수도 있다.The aluminum waste collection dust in the sludge state obtained in the secondary drainage and dewatering step is put into a vacuum belt filter or a ceramic disk filter among known mechanical devices, and a moisture content of 5 to It can be delivered after packaging (S600) by weight (g) unit in a state where moisture is removed (S500) so that it becomes 20% or less, and the aluminum waste dust obtained in the moisture removal step (S500) is heated at 1,000 to 1,400°C temperature. After the firing process (S550) for 30 to 60 minutes under the conditions, it may be delivered by packaging (S600) by weight (g) unit.

즉, 납품 방법이 2가지로 나뉠 수 있는바, 이는 고객이 원하는 조건에 알맞게 공정처리를 한 후 납품하는 방법이나, 불순물을 제거하거나 염분을 제거하는 것과는 무관하며, 아울러 수분제거 단계 이후에는 간단한 건조공정이 추가될 수 있으나 이 역시 선택사항에 불가하다.That is, the delivery method can be divided into two types. This is a method of delivery after processing suitable for the conditions desired by the customer, but it has nothing to do with removing impurities or salt, and also simple drying after the water removal step. A process may be added, but this is also not an option.

상기와 같은 과정을 자동화하여 연속 반복처리함으로써 지속적인 시멘트용 알루미나를 대체할 수 있는 대체원료로 생산 가능한 것이며, 소성 후에는 요구에 따라 분말 상태 또는 브리켓(BRIQUET) 형태로 가공 후 시멘트 제조업체는 물론 내화벽돌을 제조하는 업체 등 알루미나를 필요로하는 업체에 납품을 할 수도 있다.It can be produced as an alternative raw material that can continuously replace alumina for cement by automating the process as described above and continuously repeating it. It is also possible to supply to companies that require alumina, such as manufacturers of
